. To all whom tt'mcy concern:

"Be it known-that I, zen'zof 2the United States', 'residing at East Orange, county of'EsseX, State of New Jer.-V

lar and in which the carriers are run Without.

for example, onefcarrier'may move more rapan .attendant from on'e point to another, there 1s' danger ofcollision between carriers,

idly than the carrier ahead of it and over? take it, or, a carrier may run into another' carrier which has been stopped'.

' The object of thepresentinvention is to.

prevent the! occurrence of collisions in systems of lthe character described, and to this end theinvention comprises a novel forni of circuit-breaker apparatus adaptedto be operated when two cars come too -close together.

The present invention alsoconip'ri'ses iniproved operating means for the main hoisting and traverse controllers to be hereinafter.

described andparticularly pointed out in the claims.

In the accompanying drawings l have' illustrated a preferred forni of tlie'present inan automatic carrier running Aupon an overhead'track;.Fig. 2 being lan end elevation of' the sanie';Fig. 3 being a top vplan view; Figsl 4 and 5- being ,enlarged views showing in plan and in side elevation, respectively, the con;

troller operating means; and Fig. v6 fbeing a diagram showing the traverse motor circuit and the emergency switch for opening it'.A

, Reference being hadto the drawings, 1 indicates a carrier ofany suitable construction .adapted torun upon a track 2. The

: carrier v4il truck 3 and a s wiveled truck 4* the sideoffthecarrier. 'At the otheryend vof the carrier is along rodorstati i7- which projects azconsiderable distance beyond the oar.-

i rierythislmember being .so located that yin l case a following. carrier approaches too ,cl oselyv,."the 'said member engages. with the .vane/on the following car an in Electric Carriers, o f' which tains a carrier,

ustrated is oi .the type having a l I .t one end of the carrier, preferably at the end adjacent o the truck 3 is placed a switch 5 which is'opf. erated by turning the vane or plate -6 against moves it 4intothe circuit-opening position, so that thev following oar is brought to rest before it comes into collision with the other car. The einerg'ency switch isshownconventionally in Fig.- iwhereinS is the traverse motorl and 9.a

brake for bringing the carrier to rest when.

the circuit of the traverse motorv is inter-l rupted.

.Where the track isstraight, the member? may be given a fixed position onthe carrier,y but where curves are encountered, means in proper alinementwith t e vane onafol,- lowin car' at all points, The member7 is. there ore`s'wi'veled-at 10 to abracket-- 11 ex# ,tending from the body. of the carrier, and a link 12 is pivotally secured at its ends to thel `frame ofthe swiveled truck 4 and to the member 7 at a point .separated some distance j from the point 10. While the carrier is' ona. straight ortion of track the member' 7 reedposition with respect to the position of this member with respect to the carrier but maintains it in approximately the lsame relation to the-vaneon a following carrier as whenbotlicarriers are cna straight -piece of track. vention, Figure-1 showing inside elevation scribed, collisions between the carriers may By properly proportioning the partsdebe prevented under all ordinary conditions; butin case the relative motion of two car riers should be so' great that a collision-"cannot be avoided, theeilectfof -the collision may be minimized by, the use of a hurler at one end ottliecarrier which is adaptedtoj strike against a stifi' stop or bracket 14 at theA opposite' end of theother carrier. p

' Another feature of the' present invention consists in improved means for operatingthe traverse controller 15 and ,the hoisting controllerl. These 'controllers are-mounted onv a bracket 17 which .may be a 'ortio'nof thel -fr'ame of the carrier, so thatt e :1X-es 4of the .controllers 'are substantially `parallel. .'lo themovabl'e member of the'controllerpl is secured a beveled gearlSand on theendfof the movable nieniberof' theconti'oller ,16 is l'mounted a pinion 19.

20 isja bracket' which may conveniently be journaled upon the shaft 21 of the traverse controller and have.

. its free end-supported by means of a spring lmust 'be providedfor vkee ing'thisinember but upon entering a curve the. truck l 4 assumes an angular position with, respect .to the body of the carrier and, by reason of -80 )its connection with the member-77 varies the 22. This braclret carries a curved rack 23 the oli positions. If it is desired to hoist,

the opposite direction. vof the handle and bracket have not affected the handle 29 ispushed upwards and the rack 23 rotates the movable member of the .hoisting controller inthe proper direction.

In order to lower, the handle 29 is pulled downwards and, through the operation of the. rack 23,jthe hoisting controller is turned These operations the traverse controller, since the gear Zi'has simply been swung through a slight arc' upon the gear lS. In order to start the carrier in the `forward direction, the handle 29 is turned to theright and the traverse controller is given asimilar movement throughthe gear connection between the controller and the handle. For a backward movement of the carrienthe handle 29 is turned to thev leftland the `movable member of the traverse controller is turned in the direction op osite to that'for forward movement. It begseen that during these operations of the traverse controller no movement of the bracket20 has taken place, so that the hoisting controller has remained stationary.' If, desired, howeverboth controllers may be operated simultaneously, namely, the handle 29 may be ushed either up or down at the saine time t at it is being rotated toward the right. or. left. Means is also provided for bringing `the carrier torest at any predeterminedstation; this means com rising a stop at said sation and a -contro er-operating arm 3i onthe carrier. This arm is secured ,to one end of a short shaft journaled in the .bracket 32 secured to or forming part of the casing of the traverse controller and carrying on .its opposite end a beveled gear 33 meshinglvvith the gear 18 on the controller. When t e controller is operated in a manner previously described the arm 3l is oscillated so as to bri-ng it into the plane of the stop'BO as shown in Figs;v l and 2 and indicated in dotted lines in Fig. 5. When the carrier reaches a station, this arm strikes a stop and is swung through such an angle that the controller is vbrought to its f 01T position.
